Question

HELP PLEASEE!! The aquarium has 6 fewer yellow fish than green fish. 40% of the fish are yellow. How many green fish are in the aquarium? Show your work. Show all steps please.

Answer 1

Green fish: x
Yellow fish: x - 6

So, the total number of fish = x + (x - 6) = 2x - 6

40% of the fish are yellow, so:
0.4 (2x - 6) = x - 6
0.8x - 2.4 = x - 6
- 0.2x = - 3.6
x = 18

Thus, green fish = 18
